Resembling S. nivalis, but the rosette-leaves more narrowly cune- 
ate-obovate and more gradually narrowed to the broad petiolar base, 
acute at summit, 1.5-3 cm. long, 5-9 mm. broad, acutely dentate 
above the long-cuneate base: scape solitary, slender, 1-7 cm. high, 
minutely glandular-pilose: inflorescence spicate-racemose, in fruit 
—2.7 em. long, 3-5-flowered: lower bracts oblong or ovate, acute, 
5-8 mm. long, exceeding the flowers: pedicels 2-3 mm. long, pilose: 
calyx-tube green, hemispherical, 1525 mm. high; calyx-lobes 
oblong or narrowly deltoid, reflexed in fruit, 1.8-2 mm. long; ete 
white, lanceolate or narrowly ne acute or subacute, 1.5-2 mm 
long, 0.5-0.8 mm. wide: filaments filiform-subulate, purplish, 1-1.2 
mm. long: capsules greenish or pale-brown, 4 mm. long; the follicles 
with very at divergent beaks.— QuEBECc: very local, in sheltered 
pockets on abrupt western calcareous slopes, altitude 1000-11 
meters, Table-top Mountain, Gaspé County, August 5 and 12, 1906,

Distributed as S. nivalis, from which it differs in many characters; 
S. nivalis having the leaves more rounded-oblong to round-obovate 
and narrowed to a more definite petiole and commonly much broader 
(0.7-8 cm.). The inflorescence of S. nivalis is usually more numerously 
flowered, varying from spiciform to corymbiform; its calyx-lobes are 
from 2-3 mm. long, spreading in fruit; its oblong petals are rounded at 
summit and 1.5-2.3 mm. wide; and its capsule is mueh larger, 5-7.5 
mm. long. On Table-top Mountain the extremely local S. gaspensis 
was growing with other very localized species, Carex rupestris Allioni, 
Pyrola grandiflora Radius, Pedicularis flammea L., Campanula uni- 
flora L. and Senecio pauciflorus Pursh.

Panicle ices corymbiform; the flowers mostly on slender pedicels 
3-10 mm. long.— LaBraDor: Rama, August 20-24, 1897, J. D.

This is apparently the plant intended by Small in the North Ameri- 
can Flora as Micranthes tenuis,‘ based upon Saxifraga nivalis B. tenuis 
Wahlenb. FI. Lap. 114 (1812). Wahlenberg’ $s variety went back to 
earlier species of Rottboel and of Martens which prove to be merely 
forms of S. nivalis in which the lower branch of the inflorescence is
